You can check out availability in your area by looking at DIRECTV NOW's website or simply signing up for its free trial via the link below.Try DIRECTV NOW for freefuboTVfuboTV markets itself as a skinny bundle aimed at cord cutters, but it comes up a bit short in its NCAA tournament coverage. fuboTV takes a spot on our list of ways to watch March Madness without cable because it offers a live feed of CBS in select markets, but note that it does not offer TNT, TBS, or TruTV, so you'll have to look elsewhere for ways to watch the National Championship and Final Four games. fuboTV is a solid service, though, so you still might want to check out its free trial. After that, fuboTV costs either $39.99 per month or $44.99 per month, depending on your market.Try fuboTV for freeHulu with Live TVHulu with Live TV is a simple and solid skinny bundle. It costs $39.99 per month and offers CBS, TBS, TNT, and TruTV. The CBS live stream is available only in select markets, as is typical of skinny bundles, but the coverage is pretty solid.

TBS and TNT are easy to come by with Sling TV: you can find them in either of Sling TV's base packages, which are Sling Orange ($20 per month) and Sling Blue ($25 per month). Sling Blue also features TruTV, but you'll need to invest in the $5 per month “Comedy Extra” add-on bundle to snag the network if you start with Sling Orange instead. Sling TV offers a week-long free trial.Try Sling TV for freeFree Over-the-Air TVCBS is a broadcast television network, and experienced cord cutters know that this means you can get it for free in many areas with an over-the-air antenna. That's a little less exciting this year, since the National Championship and Final Four games are on network TV, but there will still be plenty that's worth watching on CBS. This is the most affordable way to watch March Madness without cable, so don't neglect it!Check out free over-the-air TVCBS All AccessCBS may not have the National Championship or Final Four games this year, but they still have lots of good stuff, and that means that CBS All Access belongs in any article telling you how to watch March Madness without cable.

The service starts things off with a nice week-long free trial.Try CBS All Access for freeNCAA March Madness LiveNCAA March Madness Live offers a March Madness live stream – but it also asks for a cable login.
